Homemade Christmas jumper | Arduino and RGB LEDs In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it uses rgb LEDs that are ...

LED candles are neat, but they’re very suboptimal for wish-making: you can’t blow them out. Unless you take the circuit from ...

Odds are, if you like neon lights, you’re not thrilled with the LED faux-“neon” strips that are supposed to replace them.

Engineers have developed a new way to make sharper, defect-free displays, which could improve augmented and virtual reality devices. Instead of replacing red, green, and blue light-emitting diodes ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's Grove 4 digit display. The TM1637 chip also has keyboard input capability, but it's not implemented in ...

Abstract: Considering the low electrical conductivity of the p-type contact layer, current crowding is the primary impediment to the preparation of gallium nitride green micro-light-emitting-diodes ...

You might have assumed that LED light panels would only be suitable for videographers – but this isn’t the case. While they’re definitely more commonly associated with video, the best LED panels can ...

Abstract: Ex situ low-temperature (LT)-AlN templates are employed to realize GaN-based light-emitting diodes (LEDs) on Si substrates by the combination of pulsed laser deposition and metal organic ...
